Vehicle does not move in D range, or in R position

DESCRIPTION

• Vehicle does not move when AP is depressed.

POSSIBLE CAUSE

• If the vehicle does not move in D range or R position, basically, the malfunction is in the ATX. (Vehicle will move even with a malfunction in the TCM.) Since a malfunction is in the sensor circuit or output circuit is the cause of the malfunction in the ATX, inspect the sensors, output circuit, and the related harnesses.
1. Clutch slipped, worn (D range-Forward clutch, R position-Reverse clutch, Low and reverse brake)
• Line pressure low
• Shift solenoid D malfunction
• Shift solenoid E malfunction
• Shift solenoid A malfunction
• Shift solenoid B malfunction
• Pressure control solenoid malfunction
• Body GND malfunction
• Control valve body malfunction
2. Selector lever malfunction
3. Parking mechanism not operating properly
4. Torque converter malfunction
Note
• Before following troubleshooting steps, make sure that Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted. (See BASIC INSPECTION (GENERAL (L.H.D.) SPECS. SPORT AT) [FN4A-EL].)

Diagnostic procedure

STEP

INSPECTION

ACTION

1
When vehicle is stopped on a flat, level road and engine is off, does vehicle move when pushed? (in D range or N, R positions and brake is released)
Yes
Go to next step.
No
Check for parking mechanism. (See ATX Workshop Manual (FN4A-EL).)
2
Disconnect TCM.
Is resistance between ground terminal 1P or 1O at TCM connector and body ground less than 5.0 ohms?
Yes
Go to next step.
No
Repair open ground circuit.
Reconnect TCM.
3
Inspect pressure control solenoid circuit.
Is it okay?
Yes
Overhaul control valve body and repair or replace any defective parts. (See ATX Workshop Manual (FN4A-EL).) If problem remains, overhaul transaxle and repair or replace any defective parts. (See ATX Workshop Manual (FN4A-EL).)
No
Repair or replace any defective parts.
4
• Verify test results.
- If okay, return to diagnostic index to service any additional symptoms.
- If malfunction remains, inspect related Service Bulletins and/or On-line Repair Information and perform repair or diagnosis.
• If vehicle repaired, troubleshooting completed.
• If vehicle not repaired or additional diagnostic information not available, replace TCM.
